Axial Flow Fan – Modern Industrial Equipment Required For Cooling And Air Supply Needs An Pp Frp Tube Axial Fan takes in air parallel to the axis of blades that rotates around it and forces the air out in the same direction. They can create airflow at a high rate and are capable of generating air flow in large volumes. The key reason why they are needed in industrial units is for the purpose of supplying fresh air. They can also be used to suck the air coming from return air trenches and rotary filters. They can also be used for the purpose of exhausting air out. The most common applications in which it is used are air-cooled condensers, cooling towers, air cooled heat exchangers etc.
